Title: Improvements in or relating to machinery to be employed in the doubling or folding of metallic plates or sheets
IPC: B21B47/02
Filed: 1926-10-21
Abstract: 280,691. Thomas, H. S., and Davies, W. R. Oct. 21, 1926. Angular bending.-Apparatus for doubling or folding metallic sheets wherein the doubling is effected by submitting the sheets to endwise pressure as in Specification 181,844 comprises inwardly moving pivotadly mounted members for exerting the endwise pressure; the doubled sheet is moved by a mechanically operated lifting member to a pair of rolls and thence by transfer rolls to a collecting platform or opening or other mechanism. The members 4 which effect the doubling of the metal sheet 20 by pressing on its ends are suspended pendulum fashion on spindles 5 and are provided with spaced plates 7 forming guides for blocks 8 carrying pins 9 connected to chains 10 running over sprocket wheels 11<a> - - 11<d> mounted on axles carried by the framework 6. The chains are continuously driven by gearing 13, 14, 15 from the shaft 12 so that the members 4 are brought together when the pins 9 are traversed inwards along the lower runs of the chains. Pressure plates 17 mounted on shafts 16 carrying arms 16<a> with balance weights 16<b> close on the sheet and complete the fold. The sheet to be folded rests on platforms 29, 30 and is bowed upwards bv the blade 18<a> of the lifting member 18. Platform 29 is mounted on links 31 and is adjustable as to inclination by means of a lever 3'2 to give any desired amount of overlap. The sheet is maintained in correct alignment during folding by side guides 34, 35; the guide 34 is adjustable to the width of the sheet and the guide 35 is mounted on a bell-crank lever 38 carrying an incline 39 engaged by a roller 40 on one of the members 4 so that the guide 35 moves inwards during the folding against the action of a spring 41. The lifting member 18 is counterbalanced by weights 24 on a rope 22 passing under a pulley 21 mounted in the lower slotted portion 18<c> of the lifting member and over pulleys 23 mounted on the framework. When the members 4 reach the limit of their inward movement, the edges of the sheet are moved on to shoulders 18<b> on the lifting member, which is then raised by the engagements of the chain pins 9 under projecting arms 26 of the lifting member so that the fold of the sheet is carried between the nip of the rollers 42, whence the sheet is transferred by other rollers out of the machine.

Abstract: 953,185. Spray evaporators ; drying air; revivifying silica gel. BIRS BRIT A.G. July 28, 1960 [Aug. 10, 1959], No. 26363/60. Addition to 886,533. Headings B1B and B1L. In the spray-evaporation of liquids according to the parent Specification the air supplied to the evaporator-tower is filtered atmospheric air which has been dried by passing it through two beds of silica gel I, II, the air being cooled between these two adsorption stages by contacting it with masses of concrete or porcelain in heat-regenerator 3. At the same time, the bed of silica gel III, which has been exhausted in a previous cycle, is regenerated by another current of air. This second current is heated in heat-regenerators 4 and 2, these heat-regenerators having been heated, e.g. to 80-100 C., in a previous cycle ; and the air is then raised to about 160 C. in heat-exchanger W 1  before being introduced into adsorption bed III. The air leaving adsorption bed III is used to heat regenerator 1 before it is discharged from the system. The adsorption beds are regenerated in turn ; and the regenerators are alternately heated and cooled in two groups. If desired, the stream of fresh air leaving adsorption bed II may be passed through a fifth heat-regenerator 5 and a heat-exchanger W 2  before being introduced into the evaporator-tower. The regenerator 5 may be successively heated and cooled by using it as a heat exchanger for both air streams alternately within a particular cycle.
